摘要
为了解肠球菌的抗药情况，应用含单－高浓度抗生素肉汤试管法和琼脂平皿法以及高含量纸片扩散法，检测临床标本中分离的８６珠肠球菌对庆大霉素和链霉素的高度耐药菌株（ＭＩＣｓ≥２０００μｇ／ｍｌ）。结果表明，抗庆大霉素高度耐药菌株５９株（６９％），抗链霉素高度耐药菌株５２株。全部试验菌株对万古霉素敏感。提示临床应慎用抗生素，要选择敏感药物进行有效地治疗。
he authors collected 86 clinical Enterococcus isolates. High-level resistance to gentamicin and streptomycin(MICs≥2000μg/ml)was detected by a single-concentration agar method,single-concen-tration broth microdilution and disk diffusion methods using high-content disks. Of the 86 Enterococcus isolates,there were 59 isolates with high-level gentamicin resistance and 52 isolates with high-level streptomycin resistance. All isolates had susceptibility to vancomycin.
